a new and useful Improvement in Machines for Printing Fabrics, of whichthe follow-- ing is=a specification, accompaniedby drawings forming apart of the Same;

My inventionrelat'e's to that class of fabric printing'machines in Whichthe material to V r with my"1improved mechanism for moving be printed ismovedcontinuously in contact with the periphery of a revolving drum orcylinder. or decorative designs; are imparted to the material by meansof printing rolle'rsriin ning' in contact with the material to beprinted. The printing rollers are revolvedcon'tinuously and act inSuccession, the re tating parts being connected by gearing" so" that the"impressions are placed-upon the m'a terlal 1n proper order and correctregistra tion. In" machines of this class several colors may beprintedupon the material, a"

single color being applied by each of the rollers:

My present invention is particularly de-* signed for-the printing ofWall paper. Wall paper printing machines a" Series" of rollers areusually employed'yeach contain ing a specific pattern and each beingsup- AS the terns and colors upon 1 the r'o'llere ol the indi vidiialprinting rollers aresuocessively ap plied to "the paper in regularsequence.

It'is the object of my present invention' to provide a Simple andefficient means' Whereby one or more of the p'rlnting"'rollersmay beperiodically thrown into and out of'contact Withthe paper, therebyinterrupting the sequence of patterns or colors as may be desired- Bymeans-of my present invention I am enabledtorepeat thepatt'e'rn'upon astrip of Wall paper for a predetermineddis tance; and then'tointerpOSeadistinctive pat rollers into or out ofoperatiye contact with the paperas hereinafter described; the" novel" Specification of LettersPatent.

Similar reference characters refer to" similar" parts in the difiie'rentviews:

Referringto Figi 1 ,1 denoteportionsbf the supportingsides of theframework of the machine: ln the sides' l 1 is supported' a revolving drumQ'over 'whichthepape'ris passed; in" the usual manner. Beneath therevoly'lhtz' drum 2; is a" printing rollerfi' siip' ported o'n a shafttwhidh is journaled in boxes 5* capable of a vertical movement in Ways6* in theflfrairne-iverlt of theniaehine. The shaft- Of the drum? 2 andthe shaft 4f of the 'prmtmg roller" are geared ttsg'ether by means ofgears 7 and 8, Fig. by which 10, 1 0 rotatingd'oesely" on Studs 11' heldin the framework of the math-me Eoos ely mounted uponthestndS 1 1" arecam plates 12' haw ing their rais'ed snrfac'es" 13" adapted to Contactwith a collar Itcar'riefd upon the" shaft t of the printin roller.

The cam plateS 12*are attached toithe' sides" of the gea-rslO'bynieaneofi c'lampingthumb bolts 1 5- which pass througliconcentrically curved slots 16 and re" Screwed into the gears 10,"thereby enabling? slight rotative adjustment to'begiveir to thecamplates 12'. Mpllntecl upon the cam plates 12 are the supplen'ienta lc'arnplatesl'i'; attached tothe cam plates 12 by means of the clampingthumb bolts 18 which pass through concentrically curved slots 19 and arescrewed into the cam plates 12, thereby permitting a rotative adjustmentof the supplemental cam plates 17. The curved peripheries of thesupplemental cam plates 17 correspond with the raised cam surfaces 13 ofthe cam plates 12. Each pair of cam plates 12 and 17 form in eifect asingle two part cam, the two parts being relatively adjustable to varythe effective length of the raised portion of the cam.

The journal boxes 5 are mounted upon spiral springs 20, by which theprinting roll is normally held in its highest position and in contactwith the revolving drum 2, cans ing the pattern of the printing rollerto be applied to the paper except at that period in its revolution inwhich the raised cam surface 13 and periphery 21 of the supplemental camplate 17 are brought into contact with the collar li. When this occursthe printing roll is forced radially downward, compressing the springs20 and bringing the periphery of the printing rollout of contact withthe paper, causing an interruption of the printing by the printing roll3 during the actionof the cam 12 upon the collar 14. The period of thisaction may be increased or diminished by the adjustment of thesupplemental cam plate 17 The action of the cam plate 12 relatively tothe rotative movement of the printing roll may be varied by theadjustment of the cam plate on the side of the gear 10, thereby causingthe printing roll to be moved into an inoperative position during anydesired period of its contact with the paper, causing a part or thewhole of the pattern upon the printing roll to be omitted. Otheradjustments of the mechanism may be made by varying the relative size ofthe gears 9 and 10. ,To provide for an adjustment by a change of gears,I carry the stud 11. in a plate 22 vertically adjustable on the sideframes 1,1. The teeth of the gears 9 and 10 are sufficiently long toprevent their disengagement when separated by the action of the cam 12.g Y

In the operation of my improved mechanism, the gear 10 is selectedwhich, driven by the gear 9, will give the desired relative speed to thecam 12. The cam plate 12 and supplemental plate 17 are then attached tothe gear and the assemblage mounted upon the stud 11. An adjustment isthen made of the cam plate 12 upon the gear 10 to produce the action ofthe cam at the proper period in the rotation of the printing roller. Thesupplemental cam plate 17 is then adjusted to give the desired durationto the operation of the cam. The gear 10 is then brought intoproperengagementwith the gear 9 in order to produce the movement of theprintof the 1 drum, a printing roller, collars on the print ing roller,cams engaging the collars to move the printing roller away from-thedrum, yielding means for holding the collars in contact with the cams,and means for driving the drum, printing roller, and cams atpredetermined relative angular velocities.

3. In a machine of the kind specified, a drum, a printing roller, acollar on the printing roller, a two part cam engaging the collar tomove the printing roller away from the drum, the two parts of the cambeing relatively adjustable to vary the effective length of the raisedportion of the cam, yielding means for holding the collar in contactwith the cam, and means for driving the drum, printing roller, and camat pre determined relative angular velocities.

4. In a machine of the kind specified, a drum, a printing roller, acollar on the printing roller, a two part cam engaging the collar tomove the printing roller away from the drum, the two parts ofthe cambeing relatively adjustable to vary the effective length of the raisedportion of the cam, and means for driving the drum, printing roller, andcam at predetermined relative angular velocities.

5. In a machine of the kind specified, a drum, a printing roller, a twopart rotatable cam for moving the printing roller away from the drum,the two parts of the cam being relatively adjustable to vary theeffective length of the raised portion of the cam and being alsoadjustable together about their axis, and means for rotating the drum,printing roller, and cam at predetermined relative angular velocities.

6. In a machine of the kind specified, a drum, a printing rollercarrying a gear and a collar, an adjustable stud carrying a gear and acam, the two gears being in mesh and the collar being engaged by the camto change the distance between the drum and the printing roller.
